To report someone driving without insurance, write down the vehicle’s license plate, make, model, color, and where and when you saw it, then file a complaint with local police, your state’s motor vehicle agency, or your state insurance department. For a commercial truck or bus, the report goes to the Federal Motor Carrier Safety Administration instead. You cannot look up another driver’s insurance status yourself; the agency you file with does that.
Gather the Evidence First
A tip without specifics goes nowhere. Before you contact anyone, write down the license plate number, the make, model, and color of the vehicle, and the date, time, and location where you saw it. If you were in a crash, these details will already be in the police report. If you’re reporting someone you simply know or suspect to be uninsured, your notes are the only thing giving the complaint weight.
Photos help when you can take them safely and legally. A clear shot of the plate is the single most useful piece of evidence. Witness statements add credibility. If someone else saw the same thing, get their name and phone number and ask whether they’d back up your account.
One thing you cannot do is check the driver’s insurance status yourself. Federal law bars state motor vehicle agencies from releasing personal information from their records to the public, including information tied to a specific plate. Access is limited to government agencies, law enforcement, courts, and a narrow set of authorized users.1Office of the Law Revision Counsel. 18 USC 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records Your job is to hand solid evidence to an agency that does have access.
Where to File the Report
Three types of agencies handle uninsured driving complaints. Which one to pick depends on what you saw and what you want to happen.
Local Law Enforcement
Calling the police is the most direct route, and it’s the right one if you witnessed a violation on the road or were in an accident. Officers can run the plate against law enforcement databases, verify coverage, and issue a citation on the spot or follow up later. When you file, hand over everything: your photos, witness contact information, and your written notes.
Most departments accept tips by phone, and many jurisdictions run anonymous tip lines or online portals. An anonymous report with a plate number and vehicle description can still be enough for officers to initiate a stop. Just know that a report about an uninsured driver who isn’t creating an active safety problem will sit lower on the priority list than crimes in progress or dangerous driving.
Your State’s Motor Vehicle Agency
Every state’s DMV or equivalent agency maintains registration and insurance records, and many now run electronic insurance verification systems that automatically flag vehicles whose coverage has lapsed. You can file a complaint directly with the DMV, usually by completing a form and attaching your evidence. The agency can confirm the vehicle’s insurance status and take administrative action, including suspending the vehicle’s registration or the owner’s driver’s license until proof of coverage is filed.
Some states let vehicle owners check their own insurance status through an online portal, but those tools generally won’t let you look up someone else’s vehicle. The verification systems that catch uninsured vehicles run in the background, matching insurer data against registration records without needing a public complaint.
State Insurance Department
Your state’s insurance department or commissioner’s office regulates insurance companies and enforces mandatory coverage laws. Filing here makes sense when you suspect a pattern rather than a one-time lapse. These agencies can investigate, impose fines, and require the driver to obtain coverage and file proof of financial responsibility before driving again.
Reporting Commercial Trucks and Buses
Commercial vehicles operating across state lines fall under federal insurance requirements enforced by the Federal Motor Carrier Safety Administration. If you suspect a commercial truck or bus lacks required insurance, the process is different from reporting a personal vehicle.
The FMCSA takes complaints through its National Consumer Complaint Database at nccdb.fmcsa.dot.gov, or by phone at 1-888-368-7238, Monday through Friday from 8:00 a.m. to 8:00 p.m. Eastern Time. A suspected lack of required operating authority or insurance falls under the “Motorist Safety” category, which anyone can file after observing a safety concern involving a commercial motor vehicle.2Federal Motor Carrier Safety Administration.

You can also check a carrier’s status yourself before filing. The FMCSA’s Licensing and Insurance system lets you search by USDOT number or company name to see whether a motor carrier has the required insurance filings on record.3Federal Motor Carrier Safety Administration.

If You Were Hit by an Uninsured Driver
Most people looking up how to report an uninsured driver just got hit by one. Reporting the violation still matters, but it isn’t the first thing to do.
Start with the basics. Check yourself and your passengers for injuries, call 911 if anyone is hurt, and move your vehicle out of traffic if you safely can. Always call the police to the scene. The police report creates the official record you’ll need for every insurance claim and any lawsuit that follows. When the officer arrives, stick to facts and skip speculation about the other driver’s insurance status. The officer will verify that independently.
Exchange information with the other driver even though they say they have no coverage. Get their name, phone number, driver’s license number, license plate, and vehicle details. Photograph everything: vehicle damage, road conditions, traffic signs, visible injuries. Collect contact information from witnesses.
Do not accept an offer to “handle it without insurance.” Uninsured drivers sometimes propose paying out of pocket, but costs almost always climb once hidden injuries or additional damage appear. Without a formal claim on file, you have no leverage if the other driver stops paying.
Then contact your own insurance company promptly. If you carry uninsured motorist coverage, your policy can cover medical bills and, depending on the type, vehicle damage caused by the uninsured driver. Collision coverage will also pay for your vehicle repairs regardless of fault. The sooner you report, the faster the claim moves.
What to Expect After You File
Ask for a case or reference number when you file so you can check progress. Timelines vary widely. A police report from an accident scene may produce a citation within days. A tip about a neighbor’s lapsed coverage might sit in a queue for weeks. Administrative agencies like the DMV tend to move faster when their own electronic verification system has already flagged the vehicle.
Be ready for follow-up contact. The agency may need you to clarify details, send additional photos, or give a formal statement if the case heads toward a hearing. Cooperate when they reach out. A responsive complainant makes a much stronger case than an anonymous tip no one stands behind.
